OSX error messages that indicate your Macbook Pro hard drive is dead
For those of us have have been unfortunate enough to experience a catastrophic hard drive crash in our Macbook Pro’s’ we can say that the experience is quite annoying.
The first we do when our hard disk has crashed in OSX is to go into recovery mode by pressing Control + R and while we do a verify disk to test our disk, we receive this unfortunate message “Error: This disk needs to be repaired. Click Repair. Disk.”
So you are prompted to do a repair disk in recovery mode, and while running the drive test, you get this lovely message.
Error: Disk Utility can’t repair this disk… disk, and restore your backed-up files.
This is as far as OSX goes in trying to solve drive errors, beyond this its obvious your drive is dead. Other examples of drive failure can occur while installing Yosemite itself, check this out.
“An error occurred while preparing the installation. Try running this application again.”
And if you see this “folder” while installing Yosemite, its a safe bet your drive is also dead! Time for a new hard drive.
If you suspect that your Macbook Pro hard drive may be failing, your first step should be to backup all your valuable data. Best practices here is to use a NAS or a external drive.
